Introduction
I am a Ph.D. candidate in the Mathot Lab at UAlberta investigating torpor use and foraging behaviour in black-capped chickadees. I completed my MSc thesis in the Lane Lab at USask, where I investigated intraspecific variation hibernation expression in black-tailed prairie dogs. During my HBSc degree at the University of Toronto, I completed a research project in the Rollinson lab where colleagues and I described and quantified a sexual weapon in painted turtles.

The timing and amount of foraging in birds are shaped by many of the same extrinsic factors, including temperature and daylength, as well as intrinsic factors, such as sex and age. Here, we investigate co-variation between these traits. We observed a population of 143 individually marked black-capped chickadees (Poecile atricapillus) over a 90 day...
Despite a wealth of studies documenting prey responses to perceived predation risk, researchers have only recently begun to consider how prey integrate information from multiple cues in their assessment of risk. We conduct a systematic review and meta-analysis of studies that experimentally manipulated perceived predation risk in birds and evaluate...
Many studies assume that it is beneficial for individuals of a species to be heavier, or have a higher body condition index (BCI), without accounting for the physiological relevance of variation in the composition of different body tissues. We hypothesized that the relationship between BCI and masses of physiologically important tissues (fat and le...

Hibernation is an energy-saving strategy employed by species to survive periods of low resource abundance and inclement weather. Due to the costs and benefits associated with the use of torpor and arousal during hibernation, individuals are predicted to hibernate according to their energetic state entering hibernation and their requirements followi...

Sexually coercive reproductive tactics are widespread among animals, where one sex employs specialized structures, called sexual weapons, to harass, intimidate, and/or physically force the other sex to mate. Painted turtles (Chrysemys picta) have been extremely well-studied over the last two centuries, and their mating system has been described as...
